Content 3 Letter from the Chairman

Dear shareholders, It is my pleasure to present the Annual Report and Financial Statements of Enel Chile for 2017. In the following chapters you will find a description of our operations in the electricity generation and distribution markets through our subsidiaries Enel Generación Chile and Enel Distribución Chile.

First, I would like to thank the directors, officers, and every- one who works in our company, for the job they have done this year, for the trust they have placed on this administra- tion and, above all, for supporting the new direction we are taking as a Company.

During 2017, in addition to achieving good economic re- sults, we have carried out one of the most important re- organizations that the Chilean market has seen in recent times. The Elqui plan was conceived as the means to face the changes in the electricity industry. It became essential to incorporate the non-conventional renewable energy as- sets in Chile owned by Enel Green Power Latinoamérica into Enel Chile and it was accomplished through a merger. The Enel Generación Chile PTO was also carried out suc- cessfully and offered minority shareholders of Enel Gener- ación Chile the opportunity to become a part of Enel Chile.

The Elqui plan represents the beginning of a clear and sustainable path that will allow us to successfully face well-deserved growth in a very different energy market. It is with pride that we can say that today we are the most diversified company in this sector in Chile. In Generación we rely on a total installed capacity of 7.5 GW, of which 4.7 GW are renewable energies and 2.8 GW are thermal.

They are the maximum design capacity of the generating units, corroborated with contractual satisfaction guaranteed tests made by the manufacturer of the generating equipment, in most cases. In some cases, the figures of maximum capacity may differ from the capacity declared to the regulatory authority and customers in each country. due to criteria defined by these entities and compliance to the corresponding contractual frameworks.

In 2017, electricity sales of Enel Generación Chile and its subsidiaries reached 23,356 GWh, which represents a 34% share of total sales on the National Electricity System (SEN in its Spanish acronym) including sales to customers and net sales on the spot market.
